What You'll Have When Done:
A live, low-cost Google Search Ad campaign focused on one primary, high-value service.
Time Needed: 60 minutes
Difficulty: Confident
Prerequisites:
Set Up Conversion Tracking for Paid Ads, Google Business Profile is created.
Google Ads terrifies most micro-business owners. You've heard the horror stories—someone spent £500 in three days and got nothing. Another business owner clicked their own ad by accident and burned through their weekly budget before lunch. The platform feels designed for corporations with marketing departments, not for you.
Here's the truth: Google Ads is where big companies compete. But they're playing a different game. They're chasing volume. You're chasing precision.
Your advantage isn't budget—it's focus. Whilst a national chain spreads £10,000 across hundreds of keywords hoping to dominate search results, you're investing £5 per day on the exact search term that signals someone in your town needs your service right now. They search "[emergency plumber Chelmsford]" at 11pm on a Sunday. Your ad appears. They call. You win.
This guide teaches you to launch a single, surgically targeted Google Search campaign that runs on strict budget controls. No display network. No broad keywords. No "let Google optimise for you" automation that drains accounts overnight.
Targeting: Ultra-local radius (5 miles maximum) and exact-match keywords only.
Budget Control: Fixed daily cap (£5-£10) with Manual CPC bidding—you set the maximum you'll pay per click, not Google.
Keyword Tightness: 5-10 high-intent keywords maximum. If someone searching that term isn't ready to buy, the keyword doesn't belong in your campaign.
Relevance: Your ad copy must mirror the search term exactly, and your landing page must deliver precisely what the ad promises.
Violate any pillar, and your micro budget evaporates. Follow all four, and you'll generate leads whilst competitors waste thousands.

Before You Start, Ensure You've Completed:
Step 1: Verify conversion tracking is active and working. Log into Google Ads, navigate to Tools & Settings > Measurement > Conversions. Confirm your conversion action (phone calls, form submissions, purchases) shows "Recording conversions" status.
Step 2: Create a new Google Search Campaign. Click the blue "+" button, select "New campaign," choose your conversion goal (Leads or Phone calls), and select "Search" as the campaign type. Crucially, uncheck "Include Google Display Network"—this single checkbox protects your budget from low-intent banner ad placements.
Step 3: Set a strict daily budget (£5-£10) and choose Manual CPC bidding. Under "Bidding," select "Select a bid strategy directly" and choose "Manual CPC." This prevents Google from automatically increasing your bids to "maximise conversions" and draining your account.
Step 4: Create one Ad Group containing 5-10 Exact Match keywords for your highest-value service. Use brackets to enforce exact matching: `[emergency plumber Chelmsford]`, `[24 hour plumber Chelmsford]`, `[burst pipe repair Chelmsford]`. Each keyword should represent a search term from someone ready to hire you immediately.
Step 5: Write 2 simple, relevant Responsive Search Ads that match the keywords exactly. Include your primary keyword in at least two headlines, state your unique advantage (24-hour service, same-day appointments, 15 years local experience), and end with a clear call-to-action: "Call Now for Same-Day Service."

Google offers multiple campaign types: Search, Display, Shopping, Video, Performance Max. For micro budgets, only one option survives scrutiny—Search Network Only.
Why Search Only? Every other campaign type introduces variables you cannot control on £5 per day. Display ads appear on random websites where users aren't actively searching for your service. Video ads require production quality most micro-businesses lack. Performance Max campaigns let Google decide where to spend your money—a recipe for disaster when you're operating on survival margins.
Search campaigns target people typing specific queries into Google right now. They're not passively scrolling. They're actively looking for a solution. That intent is worth paying for.
When creating your campaign, you'll see a checkbox labelled "Include Google Display Network." Uncheck it. This single action prevents your budget from leaking into banner ads on recipe blogs and news sites where clicks are cheap but conversions are non-existent.

[MEDIA:SCREENSHOT:campaign-settings-type]
Selecting "Search Network Only" and unchecking the Display Network option to protect the micro budget.
Under "Budget and bidding," you'll set two critical constraints:
Daily Budget: Start with £5. Not £50. Not "let's try £20 and see what happens." Five pounds. This forces discipline. You cannot afford to learn expensive lessons about broad match keywords or automated bidding strategies. Your budget must last long enough to gather meaningful data—at least 30 days.
Bidding Strategy: Select "Manual CPC" (cost-per-click). Google will suggest "Maximise Conversions" or "Target CPA." Ignore these suggestions. Automated bidding strategies require substantial historical data and larger budgets to function properly. On £5 per day, automation will either spend nothing (because Google can't find efficient opportunities at your budget level) or spend everything in two hours chasing low-quality clicks.
Manual CPC means you set the maximum amount you'll pay for a single click. Start with £1.50 for local service keywords, £2.50 for emergency or urgent keywords. You can adjust these bids after reviewing performance data, but you'll never wake up to discover Google spent £47 overnight because it "detected an opportunity."
[MEDIA:SCREENSHOT:manual-cpc-setting]
Switch the bidding strategy to Manual CPC to maintain absolute control over the maximum cost per click.
Under "Locations," you'll define where your ads appear. This is not the place for ambition.
Set a Tight Radius: If you're a local service business, set a 5-mile radius around your business address. Extend to 10 miles only if you genuinely service that area and the travel time doesn't kill your profit margin. Every mile you add dilutes your budget across more potential customers, many of whom will choose a closer competitor.
Target Setting: Select "People in or regularly in your targeted locations." This prevents your ads showing to someone in Manchester who once searched for "plumber Chelmsford" whilst researching a house purchase.
Ad Schedule: If you're a sole trader who can't answer calls at 3am, set your ads to run only during business hours. There's no point paying for clicks from emergency searches if you can't convert them into customers. Under "Ad schedule," select specific hours—perhaps 7am to 7pm Monday to Saturday.

Setting a tight geographical radius (e.g., 5 miles) and checking the "People in or regularly in your targeted locations" option.
Before launching, ensure your click destination is fast. Launching a campaign means sending paid traffic to your site. Not sure your landing page is fast or error-free enough to handle the clicks? NetNav's website audit checks core landing page health factors in 60 seconds—don't pay for traffic only to lose it to slow speeds.
Create one Ad Group named after your core service: "Emergency Plumbing Chelmsford" or "Wedding Photography Essex."
Now add 5-10 keywords. Not 50. Not "everything related to plumbing." Between five and ten ultra-specific, high-intent search terms.
Use Exact Match Only: Wrap each keyword in brackets: `[emergency plumber Chelmsford]`. This tells Google to show your ad only when someone types that exact phrase (or very close variants like "emergency plumbers in Chelmsford").
Without brackets, Google uses "broad match"—your ad for emergency plumbing might show for "plumbing courses Chelmsford" or "plumbing supplies Chelmsford." You'll pay for clicks from students and trade suppliers, not customers.
Example Keyword List for Emergency Plumber:
Notice the pattern? Every keyword includes your location and signals urgency or immediate need. These are not research queries. These are "I need help now" searches.
For guidance on finding these high-intent keywords without expensive tools, see our guide on Keyword Research for Very Busy Businesses.
[MEDIA:SCREENSHOT:exact-match-keywords]
Example of using brackets `[]` to enforce Exact Match keyword targeting, preventing wasted spend on irrelevant searches.
Build a Negative Keyword List: Under "Keywords" in your Ad Group, select the "Negative keywords" tab. Add 10-15 terms that signal someone is not a customer:
Someone searching "free plumber advice" or "plumbing jobs Chelmsford" will never hire you. Don't pay for their clicks.
Click "Ads & extensions" and create a Responsive Search Ad. You'll provide multiple headlines (up to 15) and descriptions (up to 4). Google tests combinations to find what performs best.
Headline Strategy:
Description Strategy:
The Relevance Rule: Your ad copy must mirror the search term, and your landing page must deliver what the ad promises. If your ad says "No call-out fee" but your website doesn't mention this, you'll pay for clicks that bounce immediately.
Don't have a dedicated landing page? Learn how to create a high-converting landing page without hiring a developer.
Before launching, navigate to "Settings" and scroll to "Conversions." Confirm your conversion action (the one you set up in Set Up Conversion Tracking for Paid Ads) is selected.
This links your campaign to your tracking. Without this connection, you'll see clicks but won't know if those clicks became customers. You'll be flying blind.
The effectiveness of this micro budget campaign relies entirely on the speed and reliability of the page the user lands on. This is one of the critical speed and security checks NetNav runs automatically across your whole site. Reviewing these metrics now can save you budget later.
Click "Publish campaign." Your ads will enter review (usually approved within 24 hours). Once approved, they'll start appearing for your exact-match keywords within your geo-radius during your scheduled hours.
First 48 Hours: Check your campaign twice daily. Look for:
First Week: Add any irrelevant search terms that triggered your ads to your negative keyword list. Google Ads shows these under "Search terms" in the Keywords section. If you see "plumbing jobs" or "plumber salary," add those as negatives immediately.
Verify Success:
🎉 Completed? You've launched a low-risk, high-intent campaign. You're ready for Calculate Your Cost Per Lead and Cost Per Customer.

Common Problems and Fixes:
Problem: Ads aren't running—impressions show zero or very low numbers.
Fix: Your daily budget might be too low relative to your bid strategy, or your geo-radius is too restrictive. Try increasing your radius to 7-10 miles or raising your maximum CPC bid by 50p. Alternatively, check if your keywords have sufficient search volume—very niche terms might only receive a few searches per month.
Problem: Spending money fast, but clicks feel low quality—high bounce rate, no conversions.
Fix: Immediately pause the campaign. Review your "Search terms" report to see what actual queries triggered your ads. Add 10-15 broad negative keywords (free, jobs, training, DIY, course, salary, apprentice, how to, tutorial, guide). Then switch any remaining broad match keywords to exact match using brackets `[]`.
Problem: Ads are running and clicks are coming in, but conversions aren't tracking.
Fix: Go back to Set Up Conversion Tracking for Paid Ads and verify the conversion tracking pixel is correctly placed on your thank-you page or confirmation page. Use Google Tag Assistant (a free Chrome extension) to confirm the tag is firing. Also check that your conversion action is properly linked to this campaign under Settings > Conversions.
